Zinc Pest on Lionel O Gauge FasTrack connecting pins of many different lengths of straight and O36 Curves and O36 Switches sold as new (to me) between 2011-2015. The problem with the pins (center and outer) having zinc pest is that they swell and become very brittle, often easily breaking off inside adjoining rails.
Here is a picture of the differences in appearance between the older pin and it's 2021 replacement.
